It’s always summer somewhere with this paradise-themed Waboba ball! The Tropical Kahuna's large foam design makes it great for pools and the whole family. It's easy to bounce on water, and can be played in any water environment. The more water it absorbs, the higher and better it bounces! Best for the pool, lake, or ocean. Great for family vacation fun. Size: 90 mm 3.5 inch diameter. Ages: 5+.
